		ZHA Yun-fei;KONG Xiang-quan;YANG Jian-yong;LIU Ding-xi;FENG Gan-sheng
		DOI:
		Objective: To evaluate visualization of sites, degree of invasion, tumor-related veins and collateral venous pathways with three dimensional contrast enhanced magnetic resonance venography(3D-CEMRV) in parasagittal meningiomas invading the dural sinuses. Methods: Ten patients with parasagittal meningiomas were examined preoperatively with 3D-CEMRV and intraarterial digital subtraction angiography(DSA). The visualization of sites, degree, tumor-related veins and collateral venous pathways in meningiomas invading the dural sinuses were recorded in consensus by two radiologists. Compared with DSA and intraoperative findings, all manifestations were assessed on source images, maximum intensity projection images(MIP) and multiplanar reconstruction images(MPR). Results: Of the 10 patients with parasagittal meningiomas, 1 appeared invasion of sinus wall, 2 partial occlusion of sinus lumina, 7 complete occlusion of sinus lumina. The visualization of the sites of 10 parasagittal meningiomas invading the dural sinuses on 3D-CEMRV was in accordance with that of DSA and intraoperative findings. For the visualization of the degree of invasion, 3D-CEMRV images were found to be equivalent to DSA images(u=0.0000, P=1.0000), in the meanwhile, MIP images combined with MPR images and source images were superior to single MIP images(u=-1.8796, P=0.0301). With multiple postprocessing display modalities of 3D-CEMRV and DSA, the rate of the visualization of tumor-related veins and collateral venous pathways was 78.26%(36/46) and 97.83%(45/46) respectively(P=0.0016). Conclusion: With 3D-CEMRV, an exact preoperative evaluation of the sites and degree of invasion in parasagittal meningiomas invading the dural sinuses are feasible. Nevertheless, for the total visualization of tumor-related veins and collateral venous pathways, 3D-CEMRV is still inferior to DSA.

	461	Correlation of 1H-MRS features with PCNA expression in cerebral astrocytoma
		WU Yue;ZHANG Xue-lin;YANG Ben-qiang;GUAN Chang-qun;LIU Wen-yuan
		DOI:
		Objective: To study the correlation between 1H-MRS, histopathology and PCNA expression. Methods: Fifty-eight patients with surgically and pathologically proved astrocytoma were analyzed. MR, 1H-MRS and MR enhancement scan were performed before operation. The ratio of metabolic material(Cho/Cr, NAA/Cho) came from different areas of tumors were calculated respectively. PCNA was stained with S-P immunohistochemical technique in 58 samples of astrocytoma. Results: The ratios of metabolic material(Cho/Cr, Cho/NAA) of astrocytoma proved to be high pathological grade were significantly higher than those astrocytoma proved to be lower pathological grade(P<0.05). Correlation between PCNA expression of different grade astrocytoma and the ratio of Cho/Cr is good(P<0.05). Conclusion: 1H-MRS has important value both in assessing the malignant grading of astrocytoma before operation and in evaluating indirect proliferating potential and prognosis of tumor cells by quantitative analyzing the ratio of metabolic material(Cho/Cr, NAA/Cho), and the correlation between the ratio of Cho/Cr and PCNA expression.

		XU Xiang-feng;YANG Jin-yi;ZHANG Zeng-li;CHENG Yu-qing;WU Guang-li
		DOI:
		Objective: To analyze the findings of isoattenuating pancreatic adenocarcinoma on multi-slice spiral CT(MSCT) and evaluate the value of curved planar reformations(CPR) in diagnosis. Methods: The CT findings of 62 pancreatic adenocarcinoma proved by surgery or clinical materials were analyzed retrospectively. The contrast relative to pancreas was observed on the basis of visual inspection during nonenhanced and biphasic enhanced scanning. CPR were generated along pancreatic duct and common bile duct. Results: Of 62 patients, 5(8.1%) had isoattenuating tumors on the basis of visual inspection during nonenhanced and biphasic enhanced scanning. The secondary signs of the five patients included an “interrupted pancreatic duct” sign(n=5), “double duct” sign(n=4), contour abnormality of the pancreatic head(n=4), and atrophic distal pancreatic parenchyma(n=1). The remaining 57 patients had visible hypoattenuating tumors on enhance CT. Conclusion: A small number of pancreatic adenocarcinomas were deemed isoattenuating on the basis of visual inspection, indirect signs such as “interrupted pancreatic duct” sign, “double duct” sign, and contour deformity of the pancreas are important indicators for the presence of tumor. CPR help to display the whole view of pancreas, pancreatic duct and common bile duct, and help to confirm the presence of tumor.

		SONG Wu-zhan;CHI Jun;WANG Jing
		DOI:
		Objective: To study the 18F-FDG metabolic imaging in breast carcinoma and the correlation between 18F-FDG uptake and the expression of HIF-1α. Method: Thirty-one patients with primary breast carcinoma diagnosed by fine needle aspiration underwent 18F-FDG metabolic imaging. Regions of interest(ROI) were drawn on the tumor(T) and contralateral normal breast tissue(NT), T/NT ratios were measured for all scans. The expression of HIF-1α was detected by immunohistochemical method. Results: In all 31 patients, 18F-FDG uptake of tumor tissue was obviously higher than that of normal tissue. The T/NT ratios of 31 tumors was 2.98±1.09, and have no relevance to the tumor size(P>0.05). Forty minutes after injecting 18F-FDG, the T/NT ratios of IDC(infiltrating ductal carcinoma) and ILC(infiltrating lobular carcinoma) were 2.98±0.97 and 2.96±1.45(P>0.05). In all 31 patients T/NT ratios ranged from 1.68 to 6.49(median: 2.73). The percentage of tumor cells expressing HIF-1α was 25.6%~78.5%(median: 56.3%), and a positive correlation was found between them(P<0.01). Conclusions: The tissue of breast carcinoma can uptake 18F-FDG obviously and has no relevance to pathologic type and tumor size, but expresses a positive correlation with HIF-1α.

		DOI:
		Objective: To investigate the clinical significance of 99mTc-DTPA renal dynamic imaging in evaluating renal function as intravenous pyelography(IVP) detection failed. Methods: Sixty-six abnormal kidneys in 64 patients which IVP detection failed were accepted for 99mTc-DTPA renal dynamic imaging. Results: 99mTc-DTPA renal dynamic imaging demonstrated that all the IVP detection failed kidneys had poor function and nonfunction, detailed as: grade 0 in 2 cases, grade I in 3 cases, grade II in 7 cases, grade III in 36 cases, grade IV in 18 cases. And the average GFR was 53.7ml/min, 35.8ml/min, 21.1ml/min, 12.8ml/min and 7.8ml/min respectively. Twenty cases which 99mTc-DTPA renal dynamic imaging showed normal function or function slightly damaged on the contralateral kidney, the affected kidney received nephrectomy, others accepted expectant treatments and mostly with good recovery. Conclusion: 99mTc-DTPA renal dynamic imaging is an ideal method to assess preoperative renal function especially the single renal function in IVP detection failed patients. It is a simple, noninvasive, with high-sensitivity and repeatability.

		YIN Xin-dao;WANG Li-ping;LU Ling-quan;WANG Li-wei;ZHANG Tai-sheng;WU Qian-zhi;GU Jian-ping
		DOI:
		Objective: To assess the role of adding T1WI to MR cholangiopancreatography in detecting micro-choledocholithiasis. Materials and Methods: A total 104 patients having choledocholithiasis from January 2005 to December 2006 were preoperatively performed by routine MRI and MRCP. Less than 5mm micro-stones of the common bile ducts were proved by surgery or ERCP following MRI scan by 1~5 days in 56/104 patients. Routine MRI scan included RF-FAST axial T1WI(TR/TE 155ms/3.4ms) and axial fast T2WI(TR/TE 15000ms/81ms) as well as coronal T2WI(TR/TE 15000ms/81ms). EXPRESS fat-saturation imaging sequences of MRCP set included five 45mm thick-sections in oblique coronal planes in the course of the bile duct and 5mm thick no-gap coronal images(source images). Maximum intensity projection(MIP) images were generated from the coronal source images. Features of common bile duct micro-calculi on T1WI and MRCP images and the sensitivities of T1WI and MRCP diagnosing for common bile duct micro-stones were analyzed. Results: Of these 56 patients, gallbladder stones were coexisted with choledocholithiasis in 30 patients and in whom 7 patients had a history records of cholecystectomy for gallstones. The signal intensities of common bile duct micro-calculi on T1WI were high relative to the low signal intensity of the bile in 47 patients. Filling-defects of hypo-intensity signals on MRCP images were shown in 33 patients. Both T1WI and combination MRCP with T1WI had a high sensitivity in detecting the common bile duct micro-calculi than MRCP alone. Statistics showed significant differences in detecting micro-stones between combination MRCP with T1WI and MRCP alone(Fisher exact test, P<0.01). Conclusion: Adding T1WI to MRCP will be helpful to provide a significant high sensitivity for diagnosing micro-calculi of the common bile ducts.

		DOI:
		Objective: To evaluate the clinical value of selective renal artery embolization for renal carcinoma, symptomatic renal angiomyolipoma and traumatic renal hemorrhage. Methods: Selective renal artery embolization was performed in 68 patients via femoral artery with Seldinger technique, 30 cases were embolized with gelatin sponge chips before operation for renal carcinoma, and 8 cases were embolized with MMC and iodized oil, and gelatin sponge for palliative treatment of advanced renal carcinoma, 6 cases were embolized with thread segments for symptomatic renal angiomyolipoma, 24 cases were embolized with self blood coagulum, gelatin sponge and/or steel coils for traumatic renal hemorrhage. Results: In renal carcinoma, after renal artery embolization during operation, less bleeding, less operation time because of clear operation field. Clinical symptoms were improved obviously 1~3 weeks after treatment, and the tumor mass was decreased evidently with an average shrinkage of 65.6%, 3 months after embolization in symptomatic renal angiomyolipoma and advanced renal carcinoma for palliative treatment. The hemorrhage had been successfully controlled by means of renal artery embolization, and the renal function was maintained as much as possible. No severe complications occurred after embolization in all the patients. Conclusion: As a minimal invasive technique, selective renal artery embolization is a safe and effective method with less complication for treatment as an adjuvant pre-operative therapy for renal carcinoma or a palliative treatment for advanced carcinoma and an effective treatment for symptomatic renal angiomyolipoma and traumatic renal hemorrhage. Renal artery embolization should be widely applied for these renal diseases.

		OUYANG Lin;LI Min;ZHOU Shui-tian;LIN Mou-gu;CHEN Xiao-wu
		DOI:
		Objective: By simulating the characters of colon nodule focus, study the influence of the colon focus characters, CT scan scheme, view window and CT virtual colonscopy(CTC) on CT finding. Materials and Methods: Make 30 nodules by using emulational material, these nodules are made into 5 different types, including 0.5cm size with hunch shape, 0.3cm size with hunch shape, 0.2cm size with hunch shape, 0.2cm size with flat shape, 0.2cm size with higher density and flat shape, each type includes 6 nodules, then place them at the colon wall. Scan these nodules with different schemes, including 8.0mm/2.5mm/17.5(slice/collimation/pitch) and 5.0mm/1.0mm/7.0, and reconstruct CTC image. Read these primary scan images with 3 different kinds of view window, then evaluate the display of these nodules. Result: At window wide 1000HU, center level -500HU, primary image and CTC image of scheme 8.0mm/2.5mm/17.5 display all 0.5cm and 0.3cm nodules, with clear brim, and the nodules size accord with their practical size, however, for 0.2cm nodules, the primary image only looms out faintly 1 higher density with flat shape nodule, CTC only looms out 3 hunch shape nodule, and 1 higher density with flat shape nodule. Primary image and CTC image of scheme 5.0mm/1.0mm/7.0 display all nodules but nodule of 0.2cm size with lower density with flat shape. At window center level -1000HU, the brim of these nodules were blurred, with “faint margin” sign. At window center level 0HU, 0.3cm and 0.2cm nodules were not displayed, 0.5cm nodule displayed dim and smaller. Conclusion: The characters of emulational colon nodule, scan scheme, view window and CTC together influence CT to detect focus, CTC is more sensitive than primary transection image in finding out small focus.
